Fig. 11. Clevelandella parapanesthiae (Kidder, 1937). Vietnamese specimens (A–B, E–G) isolated from Panesthia angustipennis cognata Bey-Bienko, 1969 and Thai I specimens (C–D) isolated from Panesthia angustipennis angustipennis (Illiger, 1801) from life (A, E–G) and after protargol impregnation (B–D). A–D. Ventral views of specimens with well-preserved body shape. Black arrowheads mark the proximal end of the adoral zone of membranelles. E–G. A strongly squeezed specimen by pressure of the cover slip, causing the body to become markedly wider and the notch at the base of the peristomial projection to be lost. The general body organization is shown in (E), the ciliary pattern of ventral and dorsal sides is shown in (F) and (G). Asterisks mark the position of the ciliary whorl (posterior suture), white arrowhead denotes the karyophore attaching to right body margin, white double arrowhead denotes the right suture. Scale bars = 30 μm.
